To all whom it may concern:

Be it known that I, Jo'snrn J. GANNON,

a citizen of the United States, residing at material that may flowby gravity, the device Port Huron, in the county of St. Clair'and State of Michigan, have'invented certain new and usefulImprovements in Combmed Discharge and Closure Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a combination discharge and closure device for containers adapted for holding granular matter or any being" particularly designed "for a container holding salt, sugar and other granular edibles or condiments.

lVIy'invention aims to furnish a container with a. closure member that normally closes a discharge opening of the container, the closure member being arranged so that the end thereof is p'ivotally held in engagement with the container so that the opposite end of the closure member may be swung to an open position to permit of granular material fiowing from the bottom of the container. The closure member is made from a blank pressed to provide a trough-like discharge chute with the side walls limiting theopening movement of the closure member and co operating with the bottom wall of the closure member in affording pivotal means for one,

end of the closure member, while the opposite end of the closure member has a lip to limit the closing movement of the closure member and at the same time, permit of the closure member being sealed. v

The construction entering into my invention will be hereinafter described and then claimed, and reference will-now be had to the drawing, wherein- Figure 1 is a perspective View of a portion of thejcontainer provided with a closure member showing the same in an open position; i

Fig. 2is a bottom plan of the closure member; c

Fig 3 is a'bottom plan of a portion of the container showing the opening for the closure member; Fig. 4 is an enlarged'longitudinal sectional View of the closure member'in a closed position;

atapering dischargeand closure material which is bent on the "dotted lines 4: 'to provide' a connectingfor bottom wall 5 and side walls 6, with said walls disposed at a right angle to the bottom wall 5 so as ,the wide. inner edge 9 of the bottom-wall 5 and c'o-operate therewith in gripping the inner'wjall 10 of the opening 3. The arrangement of the lugs 8' and the wall 5 are such that the inner end of the closure device may pivotally support said device so that the outer end of the device maybe swung in an arc, whicli'is defined by alip 11 at the outer' end of the bottom wall 5, and outturned or return bent flanges 12 of the side wall 6. These side walls have the outer ends thereof provided with arcuated edges 13 which are adapted to cooperate with the inner end of theclosure device in frictionallyf holding the device in an adjusted position in the opening3, it being noted in Figs. 4 and .5 thatthe arcuated edges 13v bind against thewall 11 at the outer end of the opening 3, while 7 the inner ends of the walls-6bind against the inner wall 10 of the opening 3. It is 7 therefore possible to shiftthe discharge and closure device by means of the lip 11, to a desired inclination relative to the wall 2 and thus'provide a discharge openingor chute for the flow ofadesired quantityof granular matter within the container 1,

d When opening the discharge and closure A device the flanges 12 of the side Wall 6 impings against the inner face of, the Wall 2, r at tapering sides of the opening 3 and thus outer face of the Wall 2 to position of the device.
